<h3>Deploy a Directory or WAR by URL</h3>
<p>Install a web application directory or ".war" file located on the Tomcat
server. If no <i>Context Path</i> is specified, the directory name or the
war file name without the ".war" extension is used as the path. The
<i>WAR or Directory URL</i> specifies a URL (including the <code>file:</code>
scheme) for either a directory or a web application archive (WAR) file. The
supported syntax for a URL referring to a WAR file is described on the Javadocs
page for the <code>java.net.JarURLConnection</code> class. Use only URLs that
refer to the entire WAR file.</p>
<p>In this example the web application located in the directory
<code>C:\path\to\foo</code> on the Tomcat server (running on Windows)
is deployed as the web application context named <code>/footoo</code>.

Tomcat server (running on Unix) is deployed as the web application
context named <code>/bar</code>. Notice that there is no <code>path</code>
parameter so the context path defaults to the name of the web application
archive file without the ".war" extension.

<p>In this example the web application located in a subdirectory named

<h3>Deploy using a Context configuration ".xml" file</h3>
<p>If the Host deployXML flag is set to true, you can install a web
application using a Context configuration ".xml" file and an optional
".war" file or web application directory. The <i>Context Path</i>
is not used when installing a web application using a context ".xml"
configuration file.</p>
<p>A Context configuration ".xml" file can contain valid XML for a
web application Context just as if it were configured in your
Tomcat <code>server.xml</code> configuration file. Here is an
example for Tomcat running on Windows:

<p>Use of the <i>WAR or Directory URL</i> is optional. When used
to select a web application ".war" file or directory it overrides any
docBase configured in the context configuration ".xml" file.</p>
<p>Here is an example of installing an application using a Context
configuration ".xml" file for Tomcat running on Windows.

<p>Otherwise, the Message will start with <code>FAIL</code> and include an
error message. Possible causes for problems include:</p>
<ul>
<li><em>Application already exists at path /foo</em>
<blockquote>
<p>The context paths for all currently running web applications must be
unique. Therefore, you must either undeploy the existing web
application using this context path, or choose a different context path
for the new one.</p>
</blockquote></li>
<li><em>Document base does not exist or is not a readable directory</em>
<blockquote>
<p>The URL specified by the <i>WAR or Directory URL:</i> field must
identify a directory on this server that contains the "unpacked" version
of a web application, or the absolute URL of a web application archive
(WAR) file that contains this application. Correct the value entered for
the <i>WAR or Directory URL:</i> field.</p>
</blockquote></li>
<li><em>Encountered exception</em>
<blockquote>
<p>An exception was encountered trying to start the new web application.
Check the Tomcat 5 logs for the details, but likely explanations include
problems parsing your <code>/WEB-INF/web.xml</code> file, or missing
classes encountered when initializing application event listeners and
filters.</p>
</blockquote></li>
<li><em>Invalid application URL was specified</em>
<blockquote>
<p>The URL for the <i>WAR or Directory URL:</i> field that you specified
was not valid. Such URLs must start with <code>file:</code>, and URLs
for a WAR file must end in ".war".</p>
</blockquote></li>
<li><em>Invalid context path was specified</em>
<blockquote>
<p>The context path must start with a slash character, unless you are
referencing the ROOT web application -- in which case the context path
must be a "/" string.</p>
</blockquote></li>
<li><em>Context path must match the directory or WAR file name:</em>
<blockquote>
If the application war or directory is deployed in your Host appBase
directory and either the Host is configured with autoDeploy=true or
liveDeploy=true, the Context path must match the directory name or
war file name without the ".war" extension.
</blockquote></li>
<li><em>Only web applications in the Host web application directory can
be deployed</em>
<blockquote>
If the Host deployXML flag is set to false this error will happen
if an attempt is made to install a web application directory or
".war" file outside of the Host appBase directory.
